Case Study: Epidermal Inclusion Cyst on the Neck in a 33-Year-Old Female
by: Ashley Baldree
At Village Dermatology in Katy and Houston, Texas, we often evaluate patients who present with long-standing nodules or growths on the skin. This case features a 33-year-old female who presented with a firm nodule on the posterior neck, ultimately diagnosed as an epidermal inclusion cyst.
Patient Presentation
A 33-year-old female presented for evaluation of a firm nodule on the right posterior neck, which had been present for 10 years. The lesion was moderate in severity but had not been previously treated.
She declined a full skin examination and requested evaluation only of the symptomatic area.
Dermatologic Examination
A focused exam of the head, lips, and neck was performed with dermatoscopy.
Findings included:
Subcutaneous cyst with a prominent follicular pore, consistent with an epidermal inclusion cyst.
Size: approximately 1.5 cm, located on the right medial trapezial/posterior neck region.
No other concerning findings were identified.
Impression and Plan
Epidermal Inclusion Cyst (L72.8)
Counseling: Epidermal inclusion cysts are benign sacs beneath the skin filled with keratin.
Expectations: They typically remain stable, though they can enlarge, rupture, or become tender if inflamed.
Plan: Observation. No treatment required at this time.
Instructions: Patient was advised to return if the cyst ruptures, becomes red, painful, or shows signs of infection.
Key Takeaway
Epidermal inclusion cysts are benign, slow-growing lesions that can often be managed conservatively. While removal may be considered for cosmetic reasons or if the cyst becomes inflamed, observation is appropriate when the lesion is stable and asymptomatic.
At Village Dermatology in Katy and Houston, TX, we provide expert evaluation and management of cysts, nodules, and other skin growths, offering both reassurance and treatment options tailored to patient needs.
